Avaliação da qualidade de óleos de fritura utilizados em restaurante universitário

Frying is a widely used method of preparing food, because it is a very fast and convenient process, and because it provides specific characteristics of color, flavor, odor, and texture, besides having great consumer acceptance. Therefore, the interest in the physiological effects that oils heated at high temperatures can cause to the human body arises. The aim of this work was to analyze the levels of frying used oil alteration in different kinds of foods served at the university restaurant at “Instituto de Biociências, Letras e Ciências Exatas” (IBILCE), in São José do Rio Preto-SP. In addition, it aims to make the restaurant aware of the good ways to fry and the commitment of providing good quality food to students and professionals of the Institute. With this purpose, determination of total polar compounds, conjugated dienoic acids, peroxide value, and fatty acid profile were analyzed. Two rapid tests were also used: 3M Fat Monitor and Oil Test kit. The results were compared with limits recommended for the disposal of oils and fats used in frying by the Brazilian Health Surveillance Agency (ANVISA), by other countries, and by other researches. Thus, it was concluded that the university restaurant provides the consumers with fried food of good quality, since none of the analyses showed results above recommended, although there is a need of improvement in the quality control of the oil used, in order to avoid unnecessary costs to the university restaurant.

Construção de códigos esféricos através do reticulado hexagonal

Códigos esféricos n-dimensionais gerados por grupos comutativos em dimensão par, n = 2m, podem ser determinados pelo quociente de reticulados m-dimensionais, quando os vetores que geram o sub-reticulado são mutuamente ortogonais [4]. Apresentamos a construção de sub-reticulados nestas condições, a partir do reticulado hexagonal, A2. Comparamos a distância mínima do código esfé- rico construído através do quociente destes reticulados com o limitante da distância mínima estabelecido em [5].

On some extension of optimal control theory

Some problems of Calculus of Variations do not have solutions in the class of classic continuous and smooth arcs. This suggests the need of a relaxation or extension of the problem ensuring the existence of a solution in some enlarged class of arcs. This work aims at the development of an extension for a more general optimal control problem with nonlinear control dynamics in which the control function takes values in some closed, but not necessarily bounded, set. To achieve this goal, we exploit the approach of R.V. Gamkrelidze based on the generalized controls, but related to discontinuous arcs. This leads to the notion of generalized impulsive control. The proposed extension links various approaches on the issue of extension found in the literature.

Mid-infrared supercontinuum generation in a suspended-core As2S3 chalcogenide microstructured optical fiber

We demonstrate the supercontinuum (SC) generation in a suspended-core As2S3 chalcogenide microstructured optical fiber (MOF). The variation of SC is investigated by changing the fiber length, pump peak power and pump wavelength. In the case of long fibers (20 and 40 cm), the SC ranges are discontinuous and stop at the wavelengths shorter than 3500 nm, due to the absorption of fiber. In the case of short fibers (1.3 and 2.4 cm), the SC ranges are continuous and can extend to the wavelengths longer than 4 μm. The SC broadening is observed when the pump peak power increases from 0.24 to 1.32 kW at 2500 nm. The SC range increases with the pump wavelength changing from 2200 to 2600 nm, corresponding to the dispersion of As2S3 MOF from the normal to anomalous region. The SC generation is simulated by the generalized nonlinear Schrödinger equation. The simulation includes the SC difference between 1.3 and 2.4 cm long fiber by 2500 nm pumping, the variation of SC with pump peak power in 2.4 cm long fiber, and the variation of SC with pump wavelength in 1.3 cm long fiber. The simulation agrees well with the experiment.

Educação ambiental nos anos finais do ensino fundamental em uma escola do campo: uma análise a partir do projeto político pedagógico

Environmental education (EE), a critical component to face the environmental crisis, must be present in formal education in a continuous, permanent and transversal way. Studies show, however, that EE occurs, often, in a sporadic and discontinuous way, and that it is mainly linked to Sciences. The objective of this study was to investigate the inclusion of environmental subjects in the Political Pedagogical Project (PPP) of a rural school, in Araraquara, SP. Through documentary analysis of the PPP, proposals for the Environmental Education for the last years of elementary education were examined. The results allowed the understanding, in a complex and contextualized way, of aspects related to the presence of environmental subjects in the school curriculum. They reveal that the suggestion of working with Environment attend the recommendations of the conference of Tbilisi and of Brazilian National Curriculum (PCN).

Foucault's heraclitism and the concept of history

Deleuze states that Foucault would have created a new relationship between men and history, a relationship other than that established by the philosophers of history. In order to specify the steps Foucault took to accomplish this invention, I shall support, according to Deleuze, Foucault s Heraclitism as the basis for a genuine Foucaultian concept of history. After outlining the risks taken by Foucault s concept of history, I observe this concept at work through the three periods that perform his thought: Archeology, Genealogy and Aesthetics of Existence. The main characters that embody his concept of history through these periods are: a) the discontinuous profile of history; b) the denaturalization of would-be unhistorical objects; c) the historical dimension of body; d) the eddies of subjectivation in history. We shall focus our inspection on the turn made along Foucault s work when he takes into a new account the theme of subjectivity, mostly in the last two volumes of the History of Sexuality. Thus, our attention turns to the subjectivity defined as a process, in order to investigate individual identity as the result of history.
